Kirby, Gig Harbor, Wash., assignor to Allied Building Components Inc., Tacoma, Wash, a corporation of Washington Filed Aug. 16, 1965, Ser. No. 479,781 2 Claims. (Cl. 16-131) ABSTRACT OF THE DISCLQSURE A socket member for mounting swinging doors having upper and lower pivot pin members comprises a case formed in two sections, a pair of tracks on one of the sections, a socket slide formed in two parts, and engaging means releasably interengaging the socket slide parts in clamping relation to the tracks in selected positions of the slide. The socket member thereby is rendered universally applicable as either an upper or lower socket member for mounting the door.

This invention pertains to pivoting door mounting assemblies of the class used in mounting safe type swinging doors. The assemblies are also useful however in mounting either single or double swinging doors in kitchens, hallways, Stairways, dens, family rooms, utility rooms, reception rooms and similar locations.

It is the general purpose of the present invention to provide a pivoting door mounting assembly characterized by the following advantages:

(1) Ease and speed of installation.

(2) Ease of adjustment in both vertical and horizontal planes, initially and during the service life of the doors.

(3) Universal application of the assembly parts to mounting both upper and lower pivots.

(4) Adaptability to prefabricated, do-it-yourself installations.

(5) Adaptability for use on doorways of standard opening sizes having either fiat jamb surfaces or jamb surfaces provided with door stops of varying thickness.

(6) Mounts the doors so that they readily are demountable.

(7) Mounts the doors so that they automatically swing closed or can be set to remain open.

(8) Durable and low in cost.

In the drawings:

FIG. 4 is a sectional view taken along line 44 of FIG. 2 and illustrating the lower mounting unit;

FIG. 5 is a transverse sectional view taken along line 55 of FIG. 3 and illustrating the construction of the pivot pin element of the upper mounting unit; and

FIG. 6 is a longitudinal sectional view taken along line 6-6 of FIG. 3 and further illustrating the construction of the pivot pin elerrient of the upper mounting unit and the manner of its reception in the socket unit thereof.

As illustrated in FIG. 1, the pivoting door mounting assembly of my invention is used to mount a cafe or similar type door 10 across a door opening defined in part by side jamb 12. The assembly includes an upper socket member, indicated generally at 14, a lower socket member indicated generally at 16, an upper pivot pin member indicated generally at 18 and a lower pivot pin member indicated generally at 20.

It is a particular feature of the invention that the upper and lower socket members basically are similar in construction and include as a common member a case which may be used interchangeably with either, thereby simplifying the construction and reducing the number of parts required for the complete assembly.

Thus upper socket member 14 includes a case 22 having a vertical section 24 and an integral horizontal section 26.

Vertical section 24- serves the function of securing the unit to jamb 12. It is provided with a longitudinal slot 28 and an aperture 30 dimensioned and located to re ceive, respectively, adjustment screw 32 and locking screw 34.

Horizontal section 26- mounts between parallel side walls a pair of spaced, parallel horizontal tracks, indicated at 36 and seen particularly in FIG. 6. The tracks in turn slidably mount a socket slide formed in two parts. The slide makes possible horizontal adjustment of the door. Its construction is illustrated particularly in FIGS. 3 and 6.

The slide is indicated generally at 38. It comprises an upper part 40 having depending longitudinal flanges along each of its longitudinal side margins. It also has a shoul dered aperture 42 dimensioned to receive clamp screw 44. Upper socket slide part 40 further is provided with a transverse opening 46 dimensioned to receive a nail or small tool used for mounting the door in the socket and demounting it therefrom, as will appear hereinafter.

The lower part of the socket slide, indicated at 48, is provided with an upwardly projecting central portion dimensioned for reception between the flanges of upper socket part 40. It also is provided with a pair of longitudinal thinned margins dimensioned to underlie tracks 36.

A threaded opening 50 extends transversely through the lower socket slide part. It receives clamp screw 44. A socket opening 52 also is provided transversely through the lower socket slide part, a spaced distance from opening 50. 7

Upper socket member 14 thus may be mounted on jamb 12 in a desired position of vertical adjustment by means of screws 32, 34. Socket slide 38 may be located in any desired position of horizontal adjustment by loosening clamp screw 44, adjusting the slide to the desired position, and then tightening down on the screw.

Lower socket member 16 similarly includes a case 54 having a vertical section 56 and a horizontal section 58. Case 54 is identical with case 22, the two units being interchangeable.

Accordingly base 56 is provided with a transverse slot 60 and spaced therefrom a transverse aperture 62. These receive, respectively, vertical adjusting screw 64 and locking screw 66 by means of which the lower socket member is fixed adjustably to door jamb 12.

Horizontal section 58 of case 54 is formed with a pair of integral, contoured side walls mounting between them a pair of tracks similar to tracks 36 of case 26. One of these is indicated at 68 of FIG. 4.

Tracks 68 mount a socket slide assembly indicated generally at 70 in FIGS. 1 and 4.

Like socket slide assembly 38, assembly 70 is formed in two cooperating, longitudinally-divided parts.

The upper part 72 is formed with a vertical projection 74 having a cam bearing surface 76 which supports the door. It also is provided with a threaded opening 78, which receives a clamp screw and with a transverse socket opening 80 which receives the lower pivot pin.

The lower socket slide part 82 is formed with a socket opening 84 which registers with socket opening 80 of the upper part. It also is provided with a shouldered, transverse opening 86 which registers with threaded opening 78 in the upper part and, cooperating with it, receives clamp screw 88.

Like upper socket member 14, lower socket member 16 is adjustable both vertically and horizontally. The vertical adjustment is secured by locating screw 64 in adjustment slot 60. The horizontal adjustment is secured by loosening clamp screw 88, sliding upper and lower parts 72, 82 of socket slide 70 to the desired location and tightening the screw.

The upper pivot pin member 18 which is received in upper socket member 14 is mounted in a dowel opening 90 provided in the inner portion of the upper edge of door 10. The assembly includes a longitudinally bored dowel pin 92, the exterior surface of which is provided with a plurality of annular serrations 94. Dowel pin 92 is sized for reception in dowel opening 90 and thus, when coated with glue, provides an efficient means for securing the upper pivot pin in the door.

Dowel pin 92 is provided with a securing flange 96 which overlies the upper edge of the door, concealing dowel opening 90. The flange is provided not only with a central aperture 98 which registers and communicates with the bore of the dowel pin, but also with a tapered, arcuate adjustment slot 100. The latter is dimensioned to receive a screw 102 in any desired position of angular adjustment of flange 96.

A stepped pivot pin 104 is received in the bore of dowel pin 92. Its lower portion is formed with an extension 106 of reduced diameter which extends completely through the open lower end of dowel pin 92 and terminates in a keeper 108. It also mounts a compression spring 110 which normally urges pivot pin 104 to an extended position.

The upper end of pivot pin 104 is sized for insertion in pivot pin opening 52 of upper socket slide 38. It is formed with an annular abutment flange 112 which, being springpressed, normally bears against the under surface of lower part 48 of socket slide 38. It will be observed from FIGS. 3 and 6, however, that, by insertion of a nail or other small implement in opening 46, pivot pin 104 may be depressed against the force of spring 110 sufliciently so that it may be slipped out of the socket opening, thus removably mounting the door.

The construction of lower pivot pin member 20 is shown particularly in FIG. 4.

It is adapted for reception in a dowel opening 114 provided in the inner portion of the lower edge of door 10. It is comprised of an integral casting preferably of a durable, wear resistant plastic.

The lower pivot pin member is provided with a securing segment 116 which comprises a dowel pin having longitudinally-arranged, radially-extending, spaced flutes 118. When coated with glue, the dowel segment may be inserted in dowel opening 114 where it securely anchors the lower pivot pin member in place.

A flange 120 of substantial extent overlies dowel opening 114. It is provided with an arcuate slot 122 not illustrated, but similar to slot 100 of upper dowel pin unit 18. It accordingly accommodates an adjustment screw 124 by means of which the lower pivot pin may be secured in any desired position of angular adjustment.

Such adjustment is important because it enables positioning bearing segment 126 of the pivot pin assembly as required to locate beveled cam surface 128 thereof in proper relation to cam surface 76 of the cooperating socket member against which it bears.

Lower pivot pin assembly 120 is completed by a pivot pin segment 130 of sut'ficient length and diameter to be received in socket openings 80, 84 of lower socket slide 70.

It accordingly is a simple matter to mount and adjust the hereindescribed pivoting door mounting assembly. First, the door jamb is marked with a vertical center line at the desired elevation. Lower socket member 16 is lined up with the mark and adjustment screw 64 applied. Lower pivot pin member 20 is inserted in the lower socket member. This pivot pin member, like the upper pivot pin member, may be factory installed.

Next, the upper socket member is placed over the preinstalled upper pivot pin member with the door held in open position. The upper socket member is pressed downwardly as far as it will go, after which vertical adjustment screw 32 is inserted in adjustment slot 28. This mounts the door.

If the installation of a double door is contemplated, the companion door is installed on the opposite side jamb in the same manner.

The two doors then are aligned, both horizontally and vertically. To align them horizontally, they are moved closer together or farther apart by loosening clamp screws 50, 88 and adjusting the position of upper and lower socket slides 38, 70. To align them vertically, adjustment screws 32, 64 are loosened in their respective slots and the socket members adjusted until the desired position has been reached. Screws 32, 64 then are tightened down, and locking screws 34, 66 inserted.

Failure of the doors to line up centrally is to be overcome by adjusting the relative positions of camming surfaces 76, 128 of the lower pivot pin assembly. This may be accomplished simply by loosening screw 124 in arcuate adjustment slot 122, putting a wrench on flange 120 and moving it angularly until camming surface 128 has been located to secure proper alignment of the meeting edges of the doors.

It thus will be apparent that by the present invention I have provided a pivoting door mounting assembly which is applicable to a variety of swinging door installations, which is installed easily, and which is adjusted effectively both initially and during the service life of the doors.

It is to be understood that the form of my invention herein shown and described is to be taken as a preferred example of the same and that various changes in the shape, size and arrangement of parts may be resorted to without departing from the spirit of my invention or the scope of the subjoined claims.
